1, JAMES GUNNING, a citizen of the United States, residing at Inan ice receptacle of slats and lined with wire netting to a from the car to enter the openings to low the easy circulation of air while retainpass lengthwise along the tubes 24; an be ing the ice. In some cases there may be ut cooled and dried by the sprays in such pas one ice receptacle. Extending completely sage, and to leave' he tubes 24 through the under one iceieceptacle 11 is a brine tan openings 31, thus producing an effective air 12, while extending part way under the circulation in the car. The drying is d other is another brine tank 13, these two .to the condensation of' w ter vapor as e tanks beingconnected by an equaliz ng pipe air is cooled.

Below each ice more effective use than in the refrigerator rece tacle, an over the chamber 15 and cars where the brine is allowed torun ou tank 13 in one case and the tank 12 n the without being sprayed. By thus using brine other, is a sloping cover or roof 17 which sprays to cool the air in the car, the melting dianapolis, in the county of Marion and brine which drops through from the super- State of Indiana, have invented a new an posed ice receptacle 11 to trickle into a filter useful Refrigerator-Car, of which the fol- 18, whence it passes to the brinetank. e lowing is a specification. roofs .17 efiectually prevent the brine in the It is the object of my invention to increase tanks from splashing out 7 upon su den the efficiency of refrigerator cars, to utilize changes in the speed of the car. more of the heat-absorbing capacity ofthe The pump 16 is preferably driven in any ice or other cooling material used, and to suitable manner, as by a belt20, from one diminish the required number of rechargings ofthe axles 21 of the car, so that whenever with ice or other cooling material.

The crosswise section of the both ends so that the air in the car will be pipe 22 is supplied with one or more spraycirc'ulated throu h them by the action of H10 nozzles 23 projecting lengthwise o the the spray. h brine may be used a numcar in both directions, into the ends of air ber of times, if desired, means being procirculation tubes 24:.

Thus the liquid returned through said return pipes is maintained both sweeter and drier.
